AbstractBackgroundAntibiotic use contributes to the rates of bacteremia, sepsis and associated mortality, particularly through lack of clearance of resistant infections following antibiotic treatment. At the same time, there is limited information on the effects of prescribing of some antibiotics vs. others, of antibiotic replacement and of reduction in prescribing on the rates of severe outcomes associated with bacterial infections.MethodsFor each of several antibiotic types/classes, we looked at associations (univariate, and multivariable for the US data) between the proportions (state-specific in the US, Clinical Commissioning Group (CCG)-specific in England) of a given antibiotic type/class among all prescribed antibiotics in the outpatient setting, and rates of outcomes (mortality with septicemia, ICD-10 codes A40-41 present on the death certificate in different age groups of adults in the US, and E. coli or MSSA bacteremia in England) per unit of antibiotic prescribing (defined as the rate of outcome divided by the rate of prescribing of all antibiotics).ResultsIn the US, prescribing of penicillins was positively associated with rates of mortality with septicemia for persons aged 75-84y and 85+y between 2014-2015, while multivariable analyses also suggest an association between the percent of individuals aged 50-64y lacking health insurance, as well as the percent of individuals aged 65-84y who are African-American and rates of mortality with septicemia. In England, prescribing of penicillins other than amoxicillin/co-amoxiclav was positively associated with rates of both MSSA and E. coli bacteremia for the period between financial years 2014/15 through 2017/18. Additionally, as time progressed, correlations between prescribing for both trimethoprim and co-amoxiclav and rates of bacteremia in England decreased, while correlations between amoxicillin prescribing and rates of bacteremia increased.ConclusionsOur results suggest that prescribing of penicillins is associated with rates of E. coli and MSSA bacteremia in England, and rates of mortality with septicemia in older US adults, which agrees with our earlier findings. Those results, as well as the related epidemiological data suggest that antibiotic replacement rather than reduction in prescribing may be the more effective mechanism for reducing the rates of severe bacterial infections.

Abstract Background Antibiotic use contributes to the rates of bacteremia, sepsis and associated mortality, particularly through lack of clearance of resistant infections following antibiotic treatment. At the same time, there is limited information on the effects of prescribing of some antibiotics vs. others on the rates of outcomes related to severe bacterial infections. Methods We looked at associations between the proportions (state-specific in the US; Clinical Commissioning Group (CCG)-specific in England) of different antibiotic types/classes among all prescribed antibiotics in the outpatient setting (oral antibiotics in the US), and rates of outcomes (mortality with sepsis, ICD-10 codes A40-41 present as either underlying or contributing causes of death on a death certificate in different age groups of US adults; E. coli as well as MSSA bacteremia in England) per unit of antibiotic prescribing (defined as the rate of outcome divided by the rate of outpatient prescribing of all antibiotics). Results In the US, prescribing of penicillins was associated with rates of mortality with sepsis for persons aged 75-84y and 85+y between 2014-2015. In England, prescribing of penicillins other than amoxicillin/co-amoxiclav was associated with rates of both MSSA and E. coli bacteremia for the period between financial years 2014/15 through 2017/18. Additionally, multivariable analysis for the US data has also shown an association between the percent of individuals aged 50-64y lacking health insurance, as well as the percent of individuals aged 65-84y who are African-American and rates of mortality with sepsis in the corresponding age groups. Conclusions Our results suggest that prescribing of penicillins is associated with rates of E. coli and MSSA bacteremia in England, and rates of mortality with sepsis in older US adults. Those results, as well as the related epidemiological data suggest that replacement of certain antibiotics, particularly penicillins in the treatment of certain syndromes should be considered for reducing the rates of outcomes related to severe bacterial infections.

AbstractBackgroundThere is limited information on the relation between antibiotic use and antibiotic resistance in the US.MethodsWe used multivariable logistic regression to relate state-specific rates of outpatient prescribing overall for fluoroquinolones, penicillins, macrolides, and cephalosporins between 2011-2014 to state-specific prevalence of resistance for select combinations of antibiotics/bacteria among catheter-associated urinary tract infections (CAUTIs) in the CDC Patient Safety Atlas data between 2011-2014 for adults aged 65+y and 19-64y, adjusting for potential confounders.ResultsRates of fluoroquinolone prescribing were positively associated with prevalence of fluoroquinolone resistance in Escherichia coli and Pseudomonas aeruginosa (both age groups), resistance to extended-spectrum (ES) cephalosporins in E. coli (aged 19-64y), and resistance to methicillin in Staphylococcus aureus (aged 19-64y). Rates of penicillin prescribing were positively associated with prevalence of resistance to fluoroquinolones in E. coli (aged 65+) and P. aeruginosa (both age groups), and resistance to ES cephalosporins in Klebsiella spp. (both age groups). Rates of cephalosporin prescribing were negatively associated with prevalence of resistance to fluoroquinolones in E. coli and resistance to ES cephalosporins in Klebsiella spp. (both age groups). Average annual temperature was positively associated with prevalence of resistance to ES cephalosporins in E. coli and P. aeruginosa, and resistance to fluoroquinolones in E. coli.ConclusionsOur results suggest that prescribing of fluoroquinolones and penicillins to US adults is associated with prevalence of antibiotic resistance, including ESBLs and MRSA. Further work is needed to understand the potential benefit of replacing fluoroquinolones and penicillins by other antibiotics for reducing prevalence of antibiotic resistance.

AbstractObjectivesRates of hospitalization with sepsis/septicemia and associated mortality in the US have risen significantly during the last two decades. Antibiotic resistance may contribute to the rates of sepsis-related outcomes through lack of clearance of bacterial infections following antibiotic treatment during different stages of infection. However, there is limited information about the relation between prevalence of resistance to various antibiotics in different bacteria and rates of sepsis-related outcomes.MethodsFor different age groups of adults (18-49y,50-64y,65-74y,75-84y,85+y) and combinations of antibiotics/bacteria, we evaluated associations between state-specific prevalence (percentage) of resistant samples for a given combination of antibiotics/bacteria among catheter-associated urinary tract infections in the CDC Antibiotic Resistance Patient Safety Atlas data between 2011-2014 and rates of hospitalization with septicemia (ICD-9 codes 038.xx present on the discharge diagnosis) reported to the Healthcare Cost and Utilization Project (HCUP), as well as rates of mortality with sepsis (ICD-10 codes A40-41.xx present on death certificate).ResultsAmong the different combinations of antibiotics/bacteria, prevalence of resistance to fluoroquinolones in E. coli had the strongest association with septicemia hospitalization rates for individuals aged over 50y, and with sepsis mortality rates for individuals aged 18-84y. A number of positive correlations between prevalence of resistance for different combinations of antibiotics/bacteria and septicemia hospitalization/sepsis mortality rates in adults were also found.ConclusionsOur findings, as well as our related work on the relation between antibiotic use and sepsis rates support the association between resistance to/use of certain antibiotics and rates of sepsis-related outcomes, suggesting the potential utility of antibiotic replacement.

AbstractBackgroundIncrease in mortality involving poisoning, particularly by narcotics, is known to have been one of the factors that affected life expectancy in the US during the last two decades, especially for white Americans and Native Americans. However, the contribution of medicaments other than narcotics to mortality in different racial/age groups is less studied.MethodsWe regressed annual rates of mortality involving poisoning by medicaments but not narcotics/psychodysleptics (ICD-10 codes T36-39.xx or T41-50.8 but not T40.xx present as either underlying or contributing causes of death), as well as annual rates of mortality for certain subcategories of the above, including mortality involving poisoning by psychotropic drugs but not narcotics/psychodysleptics (ICD-10 codes T43.xx but not T40.xx present as either underlying or contributing causes of death) in different age/racial groups for both the 2000-2011 period and the 2011-2017 period against calendar year.ResultsAnnual numbers of deaths involving poisoning by medicaments but not narcotics/psychodysleptics grew from 4,332 between 2000-2001 to 11,401 between 2016-2017, with the growth in the rates of those deaths being higher for the 2011-2017 period compared to the 2000-2011 period. The largest increases in the rates of mortality involving poisoning by medicaments but not narcotics/psychodysleptics were in non-elderly Non-Hispanic Native Americans, followed by Non-Hispanic whites. Most of those increases came from increases in the rates of mortality involving poisoning by psychotropic medications; the latter rates grew for the period of 2015-2017 vs. 2000-2002 by factors ranging from 2.75 for ages 35-44y to 5.37 for ages 55-64y.ConclusionsThere were major increases in mortality involving poisoning by non-narcotic, particularly psychotropic medicaments, especially in non-elderly non-Hispanic whites and Native Americans. Our results, and the epidemiological data on mortality involving poisoning by different drugs and medications in the US, which are quite different from the ones in many other countries support the need for a comprehensive evaluation of the effect of various drugs, including psychotropic medications on health-related outcomes, the associated mortality the does not involve poisoning being listed on a death certificate, and the impact of medication misuse.

Despite the frequent alarms that have been published about the adverse effects of antibiotic use and misuse, physicians prescribe to patients approximately fifty percent of unnecessary antimicrobials. In an attempt to decrease the emergence of antimicrobial resistance and increase awareness, a team approach is required to address this prescribing phenomenon in a feasible manner. A retrospective study was done at a one-hundred-forty-bed hospital with a representative sample size of 368 patients. Patient data was collected and analyzed by a stewardship team. The overall antibiotic inappropriate rate was 45.8%, which is relatively high and consistent with the findings of other studies mentioned in the literature. This study aimed to provide baseline epidemiological data on the use of antibiotics in a Lebanese hospital and has revealed several notable patterns of antibiotic prescribing practices among Lebanese physicians such as the use of antimicrobial drugs example penicillin was consistently high. Strong correlations were identified between the type of attending physician and antibiotic appropriateness. These findings will be important in constructing an antimicrobial stewardship program to reduce antibiotic misuse.

Abstract Background Measuring antimicrobial consumption data is a foundation of antimicrobial stewardship programs. There is data to support antimicrobial scorecard utilization to improve antibiotic use in the outpatient setting. There is a lack of data on the impact of an antimicrobial scorecard for hospitalists. Our objective was to improve antibiotic prescribing amongst the hospitalist service through the development of an antimicrobial scorecard. Methods Conducted in a 451-bed teaching hospital amongst 22 full time hospitalists. The antimicrobial scorecard for 2019 was distributed in two phases. In October 2019, baseline antibiotic prescribing data (January – September 2019) was distributed. In January 2020, a second scorecard was distributed (October – December 2019) to assess the impact of the scorecard. The scorecard distributed via e-mail to physicians included: Antibiotic days of therapy/1,000 patient care days (corrected for attending census), route of antibiotic prescribing (% intravenous (IV) vs % oral (PO)) and percentage of patients prescribed piperacillin-tazobactam (PT) for greater than 3 days. Hospitalists received their data in rank order amongst their peers. Along with the antimicrobial scorecard, recommendations from the antimicrobial stewardship team were included for hospitalists to improve their antibiotic prescribing for these initiatives. Hospitalists demographics (years of practice and gender) were collected. Descriptive statistics were utilized to analyze pre and post data. Results Sixteen (16) out of 22 (73%) hospitalists improved their antibiotic prescribing from pre- to post-scorecard (χ 2(1)=3.68, p = 0.055). The median antibiotic days of therapy/1,000 patient care days decreased from 661 pre-scorecard to 618 post-scorecard (p = 0.043). The median PT use greater than 3 days also decreased significantly, from 18% pre-scorecard to 11% post-scorecard (p = 0.0025). There was no change in % of IV antibiotic prescribing and no correlation between years of experience or gender to antibiotic prescribing. Conclusion Providing antimicrobial scorecards to our hospitalist service resulted in a significant decrease in antibiotic days of therapy/1,000 patient care days and PT prescribing beyond 3 days.

Abstract Background An estimated 12% of women experience ≥ 1 episode of urinary tract infection (UTI) annually. Incidence is bimodal, with peaks occurring in young, sexually active women (18–24 years) and in post-menopausal women. Previous studies suggest the prevalence of antimicrobial resistance (AMR) in UTI is rising; however recent AMR data for community-acquired UTI are lacking. We estimated the prevalence of AMR among US females with outpatient UTI in 2011–2019, stratified by age. Methods A retrospective, multicenter, cohort study of AMR among non-duplicate urine isolates in US females (≥ 12 years of age) from 296 institutions from 2011–2019 (BD Insights Research Database, Franklin Lakes, NJ). Phenotypes examined for Enterobacterales (ENT) were: extended spectrum β-lactamase positive (ESBL+; determined by commercial panels or intermediate/resistant to ceftriaxone, cefotaxime, ceftazidime or cefepime); nitrofurantoin (NFT) not-susceptible (NS); fluoroquinolone (FQ) NS; trimethoprim-sulfamethoxazole (TMP-SMX) NS; and NS to ≥ 2 or ≥ 3 drug classes (including ESBL+). Gram-positive phenotypes were, methicillin resistant S. aureus and S. saprophyticus and vancomycin-resistant Enterococcus. Isolates were stratified by patient age (≥ 12 to < 18, ≥ 18 to < 55, ≥ 55 to < 65, ≥ 65 to < 75, ≥ 75 years). Chi-square tests were used to evaluate AMR difference between groups. Results In total, urine isolates were collected from 106 to 296 (2011–2019) US sites. Overall, the prevalence of antimicrobial NS increased with age for all E. coli phenotypes (all P< 0.001; Table 1), and for non-E. coli ENT (all P< 0.001), except NFT NS, which decreased from 70.6% to 59.7% (P=0.002; Table 2). The greatest difference between age groups in prevalence of resistance was observed for FQ NS E.coli: 5.8% (≥ 12 to < 18 years) vs 34.5% (≥ 75 years). For the multi-drug resistant E. coli phenotypes, resistance increased with age, ranging from 4.8–22.4% and 0.9–6.5% for ≥ 2 and ≥ 3 drug NS, respectively. Overall, the prevalence of resistance for Gram-positive phenotypes increased with age (all P< 0.001; Table 3). Table 1. Prevalence of antimicrobial resistance among E. coli isolates in US females with outpatient UTI by age group. Table 2. Prevalence of antimicrobial resistance among non-E. coli ENT isolates in US females with outpatient UTI by age group. Table 3. Prevalence of antimicrobial resistance among Gram-positive isolates in US females with outpatient UTI by age group. Conclusion The prevalence of AMR in E. coli and non-E. coli ENT increased with age among US females presenting for care in the outpatient setting overall. A similar trend increase by age is also seen in Gram-positive isolates. Disclosures Vikas Gupta, PharmD, BCPS, Becton, Dickinson and Company (Employee, Shareholder)GlaxoSmithKline plc.

Background: Antibiotic resistance has increased at alarming rates, driven predominantly by antibiotic overuse. Although most antibiotic use occurs in outpatients, antimicrobial stewardship programs have primarily focused on inpatient settings. A major challenge for outpatient stewardship is the lack of accurate and accessible electronic data to target interventions. We sought to develop and validate an electronic algorithm to identify inappropriate antibiotic use for outpatients with acute bronchitis. Methods: This study was conducted within the University of Pennsylvania Health System (UPHS). We used ICD-10 diagnostic codes to identify encounters for acute bronchitis at any outpatient UPHS practice between March 15, 2017, and March 14, 2018. Exclusion criteria included underlying immunocompromising condition, other comorbidity influencing the need for antibiotics (eg, emphysema), or ICD-10 code at the same visit for a concurrent infection (eg, sinusitis). We randomly selected 300 (150 from academic practices and 150 from nonacademic practices) eligible subjects for detailed chart abstraction that assessed patient demographics and practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for assessment of the electronic algorithm. Because antibiotic use is not indicated for this study population, appropriateness was assessed based upon whether an antibiotic was prescribed or not. Results: Of 300 subjects, median age was 61 years (interquartile range, 50–68), 62% were women, 74% were seen in internal medicine (vs family medicine) practices, and 75% were seen by a physician (vs an advanced practice provider). On chart review, 167 (56%) subjects received an antibiotic. Of these subjects, 1 had documented concern for pertussis and 4 had excluding conditions for which there were no ICD-10 codes. One received an antibiotic prescription for a planned dental procedure. Thus, based on chart review, 161 (54%) subjects received antibiotics inappropriately. Using the electronic algorithm based on diagnostic codes, underlying and concurrent conditions, and prescribing data, the number of subjects with inappropriate prescribing was 170 (56%) because 3 subjects had antibiotic prescribing not noted based on chart review. The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were the following: sensitivity, 100% (161 of 161); specificity, 94% (130 of 139); positive predictive value, 95% (161 of 170); and negative predictive value, 100% (130 of 130). Conclusions: For outpatients with acute bronchitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. This algorithm could be used to efficiently assess prescribing among practices and individual clinicians. The impact of interventions based on this algorithm should be tested in future studies.Funding: NoneDisclosures: None

Abstract Teenagers are important carriers of Neisseria meningitidis, which is a leading cause of invasive meningococcal disease. In China, the carriage rate and risk factors among teenagers are unclear. The present study presents a retrospective analysis of epidemiological data for N. meningitidis carriage from 2013 to 2017 in Suizhou city, China. The carriage rates were 3.26%, 2.22%, 3.33%, 3.53% and 9.88% for 2013, 2014, 2015, 2016 and 2017, respectively. From 2014 to 2017, the carriage rate in the 15- to 19-year-old age group (teenagers) was the highest and significantly higher than that in remain age groups. Subsequently, a larger scale survey (December 2017) for carriage rate and relative risk factors (population density, time spent in the classroom, gender and antibiotics use) were investigated on the teenagers (15- to 19-year-old age) at the same school. The carriage rate was still high at 33.48% (223/663) and varied greatly from 6.56% to 52.94% in a different class. Population density of the classroom was found to be a significant risk factor for carriage, and 1.4 persons/m2 is recommended as the maximum classroom density. Further, higher male gender ratio and more time spent in the classroom were also significantly associated with higher carriage. Finally, antibiotic use was associated with a significantly lower carriage rate. All the results imply that attention should be paid to the teenagers and various measures can be taken to reduce the N. meningitidis carriage, to prevent and control the outbreak of IMD.

Abstract Objectives Understanding the current state of antibiotic treatment guidelines and prescribing practices for bacterial enteric infections is critical to inform antibiotic stewardship initiatives. This study aims to add to the current understanding through three objectives: (i) to identify and summarize published treatment guidelines for bacterial enteric infections; (ii) to describe observed antibiotic prescribing practices for bacterial enteric infections across three sentinel sites in Canada; and (iii) to assess concordance between observed antibiotic prescribing and treatment guidelines. Methods An environmental scan of treatment guidelines for bacterial enteric infections was conducted and recommendations were collated. A descriptive analysis of cases of bacterial enteric illnesses captured in FoodNet Canada’s sentinel site surveillance system between 2010 and 2018 was performed. Antibiotic-use data were self-reported by cases via an enhanced questionnaire. Results Ten treatment guidelines were identified in the environmental scan. There was substantial variation between guidelines for both when to prescribe antibiotics and which antibiotics were recommended. Of the 5877 cases of laboratory-confirmed bacterial enteric illness in the three sites, 49% of cases reported having received an antibiotic prescription. Of particular significance was the finding that 21% of verotoxigenic Escherichia coli cases received a prescription. Of the 17 antibiotics recommended in the guidelines, 14 were used in practice. In addition to these, 18 other antibiotics not included in any of the guidelines reviewed were also prescribed. Conclusions Our study suggests that a substantial proportion of enteric bacterial infections in Canada are prescribed antibiotics. These findings highlight the need to standardize treatment guidelines for enteric illnesses and could be used to inform future stewardship programme development.
